Karim D. Ghantous Posted December 1, 2015 Share Posted December 1, 2015 Fuji used polyester in Single-8, and all APS film cassettes contained film with polyester bases (you could get 40 exposures from and APS cassette). So, would polyester not be a good idea for at least some uses? I'm thinking of underwater photography where the magazines can be small but still allow a longer running time.

Premium Member David Mullen ASC Posted December 1, 2015 Premium Member Share Posted December 1, 2015 Since polyester doesn't break, it could damage a camera if it jammed -- with a cartridge design like Single-8, perhaps it wouldn't have mattered if it jammed or maybe it was a jam-proof design, I don't know. Better for the film to break than the camera... Polyester base is available for post-production stocks though. Link to comment Share on other sites More sharing options...
Freya Black Posted December 1, 2015 Share Posted December 1, 2015 Polyester film can only be spliced with tape too whereas acetate can use cement splices. No vinegar syndrome with polyester tho! :) Freya Link to comment Share on other sites More sharing options...
Kenny N Suleimanagich Posted December 1, 2015 Share Posted December 1, 2015 The recently-defunct Wittnerchrome 200D uses a polyester base, but they don't give you more film and it's not noticeably more compact than acetate (if longer runs is what you're asking about).

Marc Roessler Posted December 4, 2015 Share Posted December 4, 2015 Polyester (aka Estar) base also is problematic with regard to light piping. Not so much of a problem for print film in the lab, but it is a somewhat of a problem for 100' daylight rolls and even when loading 16mm two-chamber mags like Arri or Aaton. The light bounces around within the base and is carried far into the roll, much further than with triacetate stock. Link to comment Share on other sites More sharing options...
Maik Lobborn Posted December 27, 2015 Share Posted December 27, 2015 Wittner Chrome 200D is still available. And will -according to Wittner- remain available through 2016 and 2017 as well. They have bought the whole Agfa inventory from the last production run in 2015 and will continue to supply the filmmakers at least two years to come.

Mark Dunn Posted December 27, 2015 Share Posted December 27, 2015 The APS cassette could contain a bit more film because the frame size was smaller. The base thickness isn't significant- it's only 10% or so. Anyway a 35mm. cassette could hold 36. The only exception was one of the Ilford B/W stocks which IIRC had a very thin base to allow 72.
